BANDrBEfiDIfiG AND BUdKLE-A'ITACI-IING MACHINE.

Application filed. June 15.

This invention relates to a machine for bending metallic straps or bands and at taching buckles to an end of each hand.

More particularly, it relates to a machine for making straps or bands suitable for banding bundles of cotton ties, hoops, steel bars, or similar materials, although, of course, it could be usedfor a variety of'purposes.

An object of the invention is to provide bands suitable for use in a method of banding bundles wherein the completed bands will be tightly arranged upon the bundles and the joined part of the band will lie flat against the bundle. I

Another ob'ect is to provide bands suitable for use in a method of handing bundles wherein the bands willbe so attached'that it will be practically impossible for them to become loosened by the ends thereof slipping sidewise on each other. 7

Another object is to provide a machine which will prepare the bands so that they may be readily applied to the bundles.

Another object is to provide a method of applying bands to bundles wherein the bands will possess strength, but will at the same time, be capableof ready removal from the bundles.

Further objects and advantages will hereinafter appear.

The invention contemplates the employment of a band of thin flat stock, the ends of which are held together by being looped and clinched into a buckle.

Preferably one end of the band is fastened into the buckle before'the band and buckle are placed upon the bundle. The free end of the band may be doubled upon itself at the same time that the other end and buckle are joined.

In order to facilitate the fastening of the buckle to one end of the band and the doubling of the other end thereof upon itself, amachine is provided for performing these operations automatically.

This machine may comprise in general, means for advancing the bands to position for being fastened to the buckle, means for automatically or otherwise supplying the buckles, and means for clinching the ends of the bands.

An embodiment of the invention is hereinafter described, while the machine forming a part thereof is illustrated in the accompanying drawings; wherein,

.Fig. 5 is a longitudinal vertical section taken ou line 55 of Fig. 1;;

Fig. 6,is a transverse vertical section taken 0n line66 of Fig. 1, showing the bending rollers 1n elevation;

Fig. 7 1s a fragmentary top plan view of the machine, the yoke covering the anvil arms and links being removed;

Fig. 8 is a transverse vertical section taken on line 8-8-of Figure 1;

Fig. 9. is a plan view of the buckle; and

Fig. a perspective view of a portion of a bundle of cotton ties showing the band and. buckle in place thereon.

The .machine comprises a bed plate 1 adapted to be suitably secured to aframe or table, not shown. This bed plate is provided with a central opening 2,. and a narrower opening 8 extending centrally of the plate from one edge thereof to the first named opening.

Secured to the upper surface of the bed plate and adjacent to the longitudinal sides of the opening 2, are guide members 4 and 5. These guide members are substantially L shape and each have a slot 6 arranged near the top of the vertically extending arm thereof.

A substantially U shaped ram member 7 is provided with lugs extending; from each longitudinal; side thereof adapted to v have a sliding fit within the grooves 6 of the guides i and 5. The member 7 is provided centrally of the transverse base thereof with a forwardly projecting-head 8. Bulldozing hooks 9 and 10 are pivoteclby means of pivot pins 11dand12 to the outside of the ram upon each s1 e.

Projecting downwardly from the opposite sides of theopening 2 of the bed plate 1, are plates 13 and 14 having cam slots 15 and 16 arranged therein. The hooks 9 and 10 cam slots and 16, causing the hooks 8 and 10 to rise or fall.

Positioned upon the bed plate 1 adjacent to the left-hand end of the guides 4 and 5, are bending rollers 18 and 19, these rollers being mounted so as to rotate upon vertical axes. Rotatably mounted in. suitable bearings 20 and 21, secured to the upper part of the bed plate on the right-hand side thereof, is a crank shaft 22. A detailed description of these. bearings is not given since they may be formed in any desirable manner. A connecting rod 23 is attached in any preferred way to the crank shaft 22 at the central offset part thereof, this connecting rod 2-5 being operatively connected to the ram 7 by means of a wrist pin 24, as is clearly shown in Fi 'ure 1 of the drawing.

From the description so far given, it will readily appear that as the crank shaft 22 is rotated, the ram 7 will have areciprocatory movement within the grooves 6 of the guides at and 5 because of the movement of the connecting rod 23. At the same time, as previously described, the books 9 and 10 will have an upward and downward movement because'of the cam slots 15 and 16.

Slidably mounted upon pins 25 and 26, projecting from the left-hand edge of the bed plate 1 is a substantially L shaped pusher plate 27. Linked members 28 and 29 are operatively connected to each other and to the pusher plate 27 by means of a pin 30. Pivotally arranged upon elevated bosses 31. and 32 are bell crank anvil arms and 3%. The links 28 and 29 are pivotally connected to one end of he hell crank arms 34 and 33 respectively. As the pusher plate 27 is moved backwardly and for wardly, the bell crank arms 33 and 3 1- will, because of their connection with the links 28 and 29, swing upwardly or downwardly upon their pivotal connection to the bosses 31 and32.

A coil spring 35 connected to the lower -cnd of the downwardly projecting arm of the member 27 and to a downwardly projecting lug 36 of the bed plate 1 tends at all times to maintain the said plate 27 at the limit of its movement toward the right, thereby keeping the arms 33 and as in their raised position.

A yoke cover member 37 is arranged above the links and'the arms.

The machine may be operated manually or it may be power driven if it is so desired.

A clutch construction has been illustrated which may be used when the machine is power driven.

This clutch comprises a clutch member 38 having a reduced annular portion 39 and an enlarged portion 40. The'clutch is splined upon the crank shaft, being adapted to have a suitable movement thereon.

A bowed leaf spring 41, secured to an upstanding part 4-2 of the plate 1, has one end bearing against the portion 40 of the clutch. The clutch is thereby held in engaged position.

In order to disengage the clutch a spring pressed pin 48 sliding in the part 42 and another upstanding part 44 is provided. This pin has its engaging end provided with a cam surface so that the clutch will be moved out of engagement when the pin is advanced.

A link member i5 is connected to the opposite end of the pin and to a bell crank lever 46 pivotally arranged to the side of the plate 1.

It will be clear that whenever the lever 46 is depressed the pin will be disengaged from the portion l0 and the spring i1 will throw the clutch into engaged position. As soon as the lever 46 is released the pin will be advanced by its spring and the clutch disengaged.

For a purpose to be hereinafter described, two members 47 and 48 are arranged for transverse adjustment upon the bed plate adjacent the left hand edge of the opening 2. These members have inclined portions 49 and 50 on the side toward the ram.

The buckles which are to be used in the machine may be fed into the operative position. from any suitable form of magazine 51. While this magazine may be of the manually operative type, it is preferable that it comprise an automatic type suitably connected and synchronized to, and with, the various working parts of the machine.

In order that the completed band and buckle may be readily extracted from the machine a slot 52 is provided in the bed plate. throughavhich the band and buckle may fall.

'The method together with the operation of the machine will now be described:

A band of thin fiat stock such as a piece of cotton tie stock is placed in the machine when the parts are in the position shown in Fig. 1. This band is so placed in the machine as to lie between the hooks 9 and 10 and the head 8 of the ram 7 Of course,

it is understood that the band will be of suchlength as is suitable to properly it and operate within the machine. The band bellii 6.
